摘　　要：淋积型稀土矿床赋存种类多种多样,开采的技术方法也应有所不同。针对原地浸矿开采南岭淋积型稀土矿存在的问题,建立了一个注、收液数值模型,并据此将南岭淋积型稀土矿划分出5种地质类型,并提出相应的开采技术。Ion-type rare earth cleposits are different in geological kinds and mining technologies.Aimed at existing problems in in-situ leach mining of Nanling ion rare earth deposits,a mathematic model of in-situ dissolve immersion was established.Nanling ion rare earth deposits are classified into five geological types according to this model and corresponding mining technologies are proposed.
